Active verse Pending Firmware
There are up to two copies of firmware stored on the iRIS, they are stored in the Active and Pending regions of non-
volatile memory. The version information for both of these areas can be obtained using iLink.
Active
– current running firmware image.
Pending
– the area containing firmware image that will be used to upgrade the Active area or used as a backup if the
Active area is corrupted. It is a landing area for new firmware to be placed while the operation of the iRIS is not affected,
thus allowing for interruptions to communications a power.
Upon completion of upload of a new firmware file, the activate command is sent to the iRIS, invalidating the Active area
and forcing c copy of the pending area to the Active.
A pending version of preceded with a 9 indicates that the firmware is partially uploaded to the iRIS. For example, 91.4.3
indicates that version 1.4.3 of the firmware is part way through being uploaded to the iRIS.

iRIS Automated Upgrade Procedure (Firmware)
iLink has an automated firmware upgrade tool that supports the iRIS 270. This tool includes several checks to confirm the
validity of the components being installed.
The automated upgrade tool will automatically select the latest version of firmware.
The example given below shows a full, automatic firmware upgrade for an iRIS 270.
1. Make sure the required upgrade files are available on the computer. Ideally these should be located in the default
deployment folders listed above in section
iRIS Executive Firmware File Naming Conventions
.
2. Connect to the iRIS using iLink.
3. Click the Program button under the button under the Configuration tab.
4. Click the Auto Upgrade button.
5. Click OK to load the selected programs to the device. The progress of the upgrade can be seen on the status bar.
6. Once the process is completed, you can see a message saying "Upgrade completed successfully" on the status bar and
the iLink window will show the current software status of the device.
